SLPECIFICATION forming part of Letters Patent N 0. 695,542, dated March 18, 1902. Application filed May 2, 1901. Serial No. 53,453. (No model.)

To all whom it may concern:

zen of the United States, residing at the city of Kirkwood, in the county of St. Louis, State of Missouri, have invented a certain new anduseful Embossing-Press, of which the following is such a full, clear, and exact description as will enable anyone skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

adapted for embossing and printing letterheads, envelops, and other stationery.

My invention consists in certain novel fea-,

tures and details of construction, all of which are described in the following specification and pointed out in the claims affixed hereto.

In the accompanying drawings,which illus-' trate one form of press made in accordance with my invention, Figure 1 is a front elevation. Fig. 2 is a side elevation. Fig. 3 is a top plan view, part of the machine being broken away to better show the remaining parts. Fig. 4 is an enlarged section showing a detail of construction. Fig. 5 is an end view of the bed-plate of the machine. Fig. 6 is an enlarged end View of a portion of the inking device. Fig. 7 is a slightly-enlarged section on the line 7 7 of Fig. 3, the parts being ina diflerent position. Fig. 8, Sheet 3, is a view Fig. 9 is an isometric projection on an enlarged scale, and Fig. 10 is a sectional view showing a detail of construction. 7

Like marks of reference refer to similar parts in the several views of the drawings.

15 and 16 are the side frames of the press, which rest upon a base 17 and are connected by a cross-piece 18, upon-which rests the front end of the bed 19 of the machine. The

rear end of the bed 19 is supportedby a frame 20, also resting on the .base 17. The side frames 15 and 16 are also connected by a cross-piece 21, in which the plunger 22 works. The plunger 22 is carried by a cross-piece 23, sliding in the slotted upper ends of the side frames 15 and 16. Projecting from the cross- My invention relates to improvements in, that class of embossing-presses which are piece 23 are two studs 21, surrounded by the Be it known that I, SAMUEL OURrIs, a citi-' 30, which wrist-pins project through slots 31 in the lower end of the connecting-rods 25, as shown in Fig. 2. The length of these slots 31 is such that during the greater part of the revolution of the disk- 28 and gear-wheel 29 the connecting-rods will be simply swung on the studs 24.; but when the wrist-pins approach their lowest position they will come in contact with the ends of the slots 31, thus drawing the connecting-rods downward and through the cross-piece 23 imparting motion to the plunger 22 to bring itin contact with the die of the machine, which will be hereinafter described.

The upper ends of the connecting-rods 2-5 are protected by guards 32.

the plunger 22,so that it will make proper In order to adjust contact with the die, I provide the said plun- .ger with'a nut 33, cooperating with right and left threads 31. By rotating the nut 33 the plunger 22 can be adjusted up or down, as required..'

Situated at the rearof the shaft 27 is a shaft 35, on which is a gear-wheel-36,meshing with the gear-wheel 29 on the said shaft 27. The shaft35 is provided with a belt-wheel 37, by means of which the machine is driven. The shaft 35 is also provided with abeveled gearwheel 38, Fig. 2, meshing with a beveled gearwheel -39. The gear-wheel 39 is carried on a short shaft journaled in the bracket 40, secured to the cross-piece 18, as shown in Fig. 7. To the upper end of this shaft is secured a disk 41, the purpose of which will be hereinafter described.

Carried by the side frame 16 is a lug 43, Fig. 3, on which is pivotally mounteda segment 4.4:. To the ends of the segment 44 are attached two wire ropes 45 or other flexible connections, the opposite ends of which are attached to a sliding bar 46, carried in a guide 47, attached to the under surface of the bed 19.

on which is pivoted a connecting rod 49. This connecting-rod 49 is provided near its forward end with a notch 50, adapted to engage with a short cross-bar 51, carried by two plates 52, projecting downwardly through a slot 53 in the bottom of the bed 19 and carried by a bed-plate 54, sliding in ways formed in the bed 19. Secured to the front end of the sliding bed-plate 54 is a die 55, which is adapted to cooperate with the plunger 22,previously described. In the rear end of the sliding bed-plate 54 is formed a recess 56, in which is contained a vessel 57, adapted to contain ink for inking the die 55. In this vessel 57 is journaled the inking-roller 58. Secured to the vessel 57 is a scraper 59 for removing the superfluous ink from the roller 58. On the shaft of the roller 58 is secured a wheel 60 for rotating the said roller, as will be hereinafter described. In the front end of the bed 19 is an opening 61, adapted to receive the end of the connecting-rod 49, and at the entrance of the opening 61 is a beveled block 62, adapted to make contact with the beveled end 63 of the connecting-rod 49, and thus raise it out of engagement with the crossbar 51. The segment 44 is connected to the disk 41 by means of a connecting-rod 65. This connecting-rod 65 is slightly longer than the distance of the point at which it is connected to the disk from the center of the disk, and thus a variable movement is imparted to the segment 44, so that the bed-plate will receive the greatest part of this motion during about one half of the revolution of the disk 41, while during the remaining half it will make but a slight movement. On the disk 41 are two camtracks 66 and 67. Running on the cam-tracks 66 and 67 are two cam-wheels 68, one of which is shown in detail in Fig. 4. Each of the camwheels 68 is carried by a vertically-sliding bar 69, sliding in a guide 70, carried by a plate 71, secured to the side frame 16. Resting on one of the sliding bars 69, controlled by the outer cam 66, is a lever 72, pivoted at 73 to an arm 74, carried by the bed 19. This lever 72 is in turn pivoted to an arm 75, secured to a rock-shaft 76. The rock-shaft 76 is pivoted in frames 77 and 78, carried by the bed 19. Projecting from the rock-shaft 76 are two arms 80,adapted to vertically reciprocate a frame 81. The frame 81 is dovetailed at its lower end, so that the inking-block 82 may be removably secured thereto by sliding the said block laterally on said dovetailed portion. The inking-block 82 has on its bottom a guideplate 83, Fig. 7, through which passes a strip 84 of suitable flexible material for inking the die 55. The strip 84 is secured at one end by pins 85, secured in the block, and at the other end by pins 86 on a shaft 87, which shaft is supported by uprights 88,carried by the block. At one end the shaft 87 is provided with a ratchet-wheel 89, Fig. 6, by means of which the proper tension can be given to the strip 84. The block 82 is also provided at one end with a downwardly-projecting rib 90, which is adapted to come in contact with the wheel 60 of the inking-roller, and thus rotating the inking-roller. Resting upon the other sliding bar 69, which is operated by the cam 67, is an arm 92, carried by a rock-shaft 93, similar to the rock-shaft 76, hereinbefore described. The rock shaft 93 is carried in frames similar. to the frames carrying the rock-shaft 76 and operates similar parts, which are numbered the same as the parts corresponding, hereinbefore described. In addition to these parts the frame 81, operated by the arm 92, is provided with brackets 94, carrying rollers-95, over which passes a strip 96 of paper or other suitable material for wiping the face of the die 55. This strip of paper 96 is carried 011 a roll 97 and is wound upon the roll 98 in the usual manner by any suitable mechanism. The frames 81 are normally held in their raised position by means of coil-springs 79, secured at one end to said frames and at the other to the side frames 77 and 78, as shown in detail in Fig. 10.

Secured to the front end of the bed 19 by means of L-shaped plates 99 is a work-table 100. In the rear end of this work-table 100 is placed a thin metal plate 101, with an opening therein through which the plunger 22 cooperates with the die 55.

The operation of my press is as follows: Power is applied to the parts by means of the belt-wheel 37, thus rotating the shaft 35. The motion of the shaft 35 is communicated, by means of the wheels 38 and 39, to the disk 41. The movement of the disk 41 is communicated, through the connecting-rod 65, to the pivoted segment44 and thence to the movable bed-plate 54. When the parts are in the position shown in Fig. 2, the rear or inking block 82 is forced down against the die 55 by the action of the cam 66 on the disk 41, thus inking the said die 55. As the die is carried forward the front or wiping block 82 is forced down against the die by means of the cam 67. The movement of the die whilein contact with the strip 96 around said block 82 removes the superfluous ink from the face of the die. As the die nears the front end of the press the movement will become slower, owing to the form of connection between the disk 41 and the segment 44, as hereinbefore described. When the die reaches its proper position under the plunger 22, the block 62 will lift the connecting-rod 49 out of contact with the bar 51, thus allowing the die to remain in this position while the connecting-rod makes a slight movement forward. As the inkingroller 58 passes beneath the inking-block 82 the said platen is forced down against the roller by means of the cam 66, and thus ink is applied to the strip 84. The rotation of the ink-roller 58 is insured by the 'contactof the strip 90 with the wheel 60 on the shaft of the inking-roller. When the bed-plate 54 moves to the rear, the inking-block 82 is raised, so as to take it out of contact with the roller 58. The work is placed on the metal portion 101 of the work-table 100 and over the opening in said metal plate and is forced down against the die 55 by means of the plunger 22. The plunger is forced downward by means of the wrist-pinsBO on the disk 28 and the wheel 29 coming in contact with the lower ends of the slots 31 in the connecting-rods 25.
